Equflow Tubeholder for Single Use Flowmeters
  • Specifically designed to expedite the exchanging of the flow tube in single-use applications
  • Thanks to its simple design the exchange of the flow tube including calibration can be realized within seconds

In the Biotechnological and Pharmaceutical industries, hygiene is of the utmost importance.
Single- use applications are becoming the norm in these industries for their time and cost saving benefits.

This tube holder was specifically designed to expedite the exchange of the flow tube in single- use applications. Thanks to its simple design the exchange of the flow tube including calibration can be realized within seconds.

The entire exchanging and calibrating process is limited to scanning a calibration code with the help of a bar code reader and subsequently measuring can continue to take place. The exchanging of a flow device has never been so easy and fast.

As an extra option, Equflow is able to deliver pre-packed and gamma radiated flow tubes. Through this innovative and powerful new tool inter-unit variation is eliminated while high accuracy is maintained.

Its robust design is particularly suitable for more solid devices. The tubeholder is also suitable for PFA flow meters.


  • Performs a fast exchange of the flow tubes.
  • High resolution square wave output
  • Flow measuring with revolutionary Infra-Red turbine rotor reflection
  • PVDF for high chemical and corrosive resistance
  • Also suitable for opaque liquids
  • PVDF meet all the requirements of the US Pharmacopeia Class VI
  • BSE/TSE certificate available
  • Gamma stable up to 50 kGy
  • Tube can be sterilized up to 140°C

All wetted parts are made of PVDF with Ruby bearing.
